"We also audit a selection of our suppliers to check compliance with our company’s quality standards. Our suppliers all conform to those accredited assurance schemes relevant to their geographical location and product supplied. These assurance schemes must also comply with all EU legislation.

In addition, we have numerous other service providers and property contractors – these are subject to a separate due-diligence process managed on our behalf by a third party. 

...

In June 2018, we completed our first unannounced audit on a supplier to monitor compliance in a number of areas. We will continue to carry out unannounced audits in this financial year, so enabling us to achieve further insight into our supply chains.

...

To ensure that all suppliers and contractors comply with our values and ethics, we have a robust supply chain compliance programme. This comprises:

• maintaining a risk register to identify and rank commercial suppliers in terms of risk.

• conducting audits on a 12 to 18-month rotation, including detailed walk-arounds of suppliers’ premises and welfare facilities (where applicable).

• reviewing suppliers’ policy statements on ethical matters, including slavery and human-trafficking.

• speaking to staff employed by suppliers to investigate working practices.

• developing action plans to deal with those suppliers which have not responded to our request to adhere to the Supplier Charter.

We have a cross-functional compliance team, with senior personnel from the following departments: Legal, Commercial, Audit and Personnel."
